The unparalleled rate in population explosion and advancements in technology has created alarming impacts on the society. This has urged the need for vigilant and efficient data mining of these phenomena. Petroleum being an indispensible part of life has escorted to several detrimental results. Air and water are the major elements which fall prey to this. The present study involves rigorous scrutinizing with statistical analysis of test data carried out on water samples collected from petrol pumps and automobile service stations for the determination of nature of configuration. The samples were collected at regular time intervals and at the fixed place irrespective of the weather and climatic conditions that prevailed. The haphazardness or fuzziness of the amount of contamination present in water recipients due to petroleum products is being evaluated using regression analysis and the runs test. It is found that organic and inorganic chemicals are more in the collected sample that leads to chemical oxygen demand (COD) and the same was reduced using activated rice husk as an adsorbent. A case study involving its harmful effects on concrete is accessed via Scanning Electron Microscope (SEM) tests.

The determination of strength properties i.e., compressive strength (CS) is essential to estimate the load at which the concrete members may crack especially in aggressive environment. The paper reports an experimental investigation on deterioration of used engine oil (UEO) soaked concrete with respect to its strength properties. Also, it is found that this deteriorating effect is lessened with partial replacement of silica fumes (SF). The CS analysis was done with a water-concrete ratio of 0.49 with nine percentage replacements of SF (0, 5, 10, 15, 20, 25, 30, 35, 40 and 45) with water curing and UEO soaking. The soaking in two different liquids was essential in order to throw light on the detrimental effects of UEO on the CS of concrete. The results of the experiments showed that 20% replacement of SF in concrete was optimum to attain maximum CS. A mathematical model based on Abrams' law has been developed to evaluate the strength characteristics of concrete subjected to UEO soaking. The developed model facilitates the prediction of CS based on curing time in water and soaking time in UEO and also the quantity of SF used. The accuracy of the developed model is evaluated and good agreements with the ground truth values are found.

Recycling of organic wastes from gardens by converting them into stabilized decomposed products known as compost or organic manure is the basis for sustainable crop production systems. Compost not only supplies plant nutrients but also improves the soil physico-chemical properties and support the activities of beneficial microorganisms and soil fauna. High vegetable oil yield potential (4-6 t ha -1 of oil) of Oil Palm (Elaeis guineensis Jacq.) has been one of the the main driving forces behind promoting this crop for cultivation under irrigated conditions by the Government of India. The yield levels of 4-6 tonnes ha -1 of oil are possible provided the crop is supplied with all the necessary inputs. With an oil yield of 4-6 tonnes which accounts for about 20 % of the fresh fruit bunches (FFB), the total biomass that is harvested in the form of FFB will be 25 tonnes or more.
